Honestly like the other guys are saying here just throw a grab in. Just by grabbing you will not only throw in the steeze factor of the grab, but grabbing will keep your arms and legs from flailing around in the air
find a nice little 20ft jump. do a lot of threes off it just barely clearing the knuckle, go faster and set the three exactly the same. you will still be in the air when your done three and naturally will go to five.
If you can get the 5, but need it to look better reach for a grab. You might not always get the grab, but being tucked up reaching for a grab typically looks better than being completely penciled out.
